IMPROVEMENT IN MACHINES FOR MOLDING CLAY TOBACCO-PIPES.

Specification forming part of Letters Patent No. 190,977, dated May 22,1877 application filed November 3, 1876.

To all whom it may concern Be it known that I, JOSEPH G. OLIVER, of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented a new and useful Improvement in Apparatus for Molding ClayTobacco-Pipes; and I do hereby declare the following to be a clear andexact description of the nature thereof, suffieient to enable othersskilled in the art to which my inventionappertains to fully understand,make, and use the same, reference being had to the accompanyingdrawings, making part of this specification, in which- Figures 1 and 2are side elevations of the apparatus embodying my invention. -Fig. 3 isa top or plan view thereof. Fig. 4 isa transverse section in line a: m,Fig. 3. Fig. 5 is an end view of the mold-carrier. Fig. 6 is a centrallongitudinal section of a portion in line 00 m, Fig. 3. Fig. 7 is a sideview of a modification.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a rotary cylinder or table carrying one or moreautomatically opening and closing molds, which are hinged to thecylinder or table, and operated by embracing and engaging arms. It alsoconsists of novel means for filling or feeding the molds. It alsoconsists of a clamp for holding the molds during the operation ofmolding the bowl and stem of the pipe. It further consists of means foradjusting the plunger that forms the cavity of the bowl, so that it maybe set for pipes of diiferent angles and sizes, and form bowls ofuniform thickness. It also consists of means for adjusting the borerthat forms the bore of the stem, so that it may be set for pipes ofdifferent angles and sizes.

Referring to the drawings, A B represent a frame, on which is mounted arevolving cylinder or table, 0, to which is pivoted one or moresectional molds, D, the contour of the working faces of each of which isthat of a tobacco-pipe.

Aside of the mold D there are arms E, which pass through the cylinder ortable (3 and receive advancing and receding motion by means of a cam, a,which, located adjacent to the cylinder or table, is fixed in position.The upper or outer ends of the arms are hooked shaped, and they areadapted to engage with pins b projecting laterally from each section ofthe mold.

F represents a forked arm, which is pivoted to the frame A B, andoverhangs the mold that is uppermost or presented to it.

Rising and lowering motions are imparted to the arm F by means of armsat d, the arm d being operated by a can], e, on the main shaft f. To thearm 01 there is also pivoted an arm, d, to which is pivoted avertically-extending plunger, G, whose lower end is of the contour ofthe inner face of the bowl of a tobacco-pipe, and it is so located thatas it descends it will enter the portion of the mold corresponding tothe bowl of the pipe. This plunger G has its hearings on a bar or plate,H, which is fitted to horizontal pieces 6 of the frame A B, said pieces0 having curved slots f, in which are fitted set-screws, by means ofwhich the plunger may be set at various angles and moved in thedirection of the length of the apparatus, so as to adapt said plungerfor molding pipes of various sizes.

J represents a bed, which is jointed to ears K secured to the frame A B,and located adjacent to the upper face of the cylinder or table 0 at theend of the mold, where the bore of the pipe is to be formed. In the earsK there are curved slots g, in which are fitted the axial bolts orscrews of the bed J. On the bed there is mounted and guided a carriage,L, which carries a wire, M, which is adapted to penetrate the clay inthe mold D and form the bore of the stem of the pipe. To the carriage Lthere is pivoted an arm or bar, N, which is formed of a series ofjointed sections, and it receives reciprocating motion from a slide, P,with which engages a cam, h, secured to the main shaft f.

It will be seen that by means of the axial carriage J, slots g, andjointed arm N, the boring wire may be adjusted or made to assume variousangles, and raised and lowered so as to form bores in the pipe-stems ofvarious angles and various sizes.

R represents a hopper, which is located with its discharge-spoutadjacent to the bowl portion of the mold D. In the hopper is a rotaryspiral conveyor, and its hub is hollow for the passage of areciprocating plunger, S,

power being communicated to the plunger and conveyor by means of cams,pulleys, or other proper means.

The cylinder or table 0 will have an intermittent motion, and power willbe communi cated thereto in any desired manner. In the present case saidpower is derived from the main shaft through the medium of a tappet, f,secured thereto and engaging with radial arms f on the cylinder ortable, as more readily seen in Figs. 1 and 5.

The operation is as follows: Power will be communicated to the variousshafts, and the hopper R properly supplied with clay. The mold adjacentto the discharge-spout will be closed, this being occasioned by the armsE, which, forced out by the cam a, embrace the sides of the mold. Thespiral conveyer having pressed a quantity of clay to the discharge-spoutof the hopper, the plunger S receives motion toward the discharge-spout,and thus injects a quantity of clay into the bowl portion of the face ofthe mold, said clay diffusing itself through both bowl and stem portionsof the face of the mold,and thus receives the outside shape of a pipe.The cylinder or table 0, revolving, carries the filled mold to theplunger G, and a fresh mold is presented to the discharge-spout of thehopper. Ii: the meantime the arm F descends and locks the sections .ofthe filled mold, the cylinder or table having ceased its rotation. Theplunger G now enters the bowl portion of the filled mold, thus formingthe cavity of the bowl, and the carriage L advances the wire M into thestem portion of the filled mold, thus forming the bore of the stem. Theplunger, boring-Wire, and locking-arm having returned to their normalpositions, the cylinder or table continues its rotation, and, owing tothe cam a, the arms E are drawn inward or downward, thus depriving thefilled mold of the support of said arms, and at the same time engagingwith the pins b, whereby the sections of the molds are separated and themold is opened, so that the molded pipe may be removed. In the meantimeanother filled mold has advanced to the plunger G, and a fresh mold ispresented to the discharge-spout of the hopper. After a mold has beenemptied, the arms E are again operated by the cam a, so as to close thesections of the mold when said mold reaches the discharge-spout of thehopper, and it is filled,carried to the plunger and boring-wire, openedand discharged, the operations being repeated and continued, as desired.

It will be seen that the plunger may be set at any angle by properlyadjusting the bar H in the slots f, and also moved longitudinally orhorizontally for pipes of different lengths.

In order to adapt the plunger for bowls of varying depths, theconnection between the rod of the plunger and the arm d" is by means ofa boss, g, through which the rod is passed,

and to which is connected a pin for attachment of the arm (1. Theplunger may be raised and lowered on the boss g, and, by means of aset-screw, provision is had for bolding said plunger in the adjustedvertical position.

The carriage L may also be raised and lowered on the cheeks or ears K,so as to provide horizontal adjustments for the boring-wire, and, owingto the axial connection of the bed J to the cheeks or ears K, the boringwire may be adjusted relatively to the angular set of the stem of thepipe. These adjusting movements will be assisted by the jointed sectionsof the bar N as said sections permit the rising and lowering of thecarriage L, and also conformation of the bar to the angle imparted tothe carriage.

In order to prevent the plunger forming bowls of irregular thicknesses,provision is also made for the transverse adjustment of the plunger. Forthis purpose the bearings or guides T of the rod of the plunger aremovable in the bar H, whereby the head of the plunger may be set trueover the mold, and there will be an equal thickness of clay between theface of the plunger and face of the molds, thus making anequally-balanced pipe. Set-screws are passed through the bar H, and,bearing against the hearings or guides T, serve to hold the plunger inits transverselyadjusted position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a rotary cylinder or table, of one or moreautomatically opening and closing molds, which are hinged thereto andoperated by sliding arms, which embrace and engage with the sides of themolds, substantially as and for the purpose set forth.

2. The hopper provided with a spiral conveyer and plunger, substantiallyas and for the purpose set forth.

3. An injecting-filling plunger, in combination with molds,substantially as and for the purpose set forth.

4. The combination, with the sectional molds D, of the clamp F,substantially as and for the purpose set forth.

5. The plunger made transversely adjustable by means of the movablebearings or guides T, substantially as and for the purpose set forth.

6. The plunger G, made adjustable angularly, horizontally, andvertically, substantially as and for the purpose set forth.

7. The boring-wire M, made adjustable angularly, horizontally, andvertically, substantially as and for the purpose set forth.
